Piping Connection Precautions

WARNING

WHEN CONNECTING REFRIGERANT PIPING, DO NOT LET SUBSTANCES OR GASES OTHER THAN THE SPECIFIED REFRIGERANT ENTER THE UNIT. THE PRESENCE OF OTHER GASES OR SUBSTANCES WILL LOWER THE UNIT'S CAPACITY, AND CAN CAUSE ABNORMALLY HIGH PRESSURE IN THE REFRIGERATION CYCLE. THIS CAN CAUSE EXPLOSION AND INJURY.

Note on Pipe Length

The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal efficiency is tested on units with a pipe length of 5 meters (16.5ft). ( In North America, the standard pipe length is 7.5m (25'). For the R290 refrigerant models, no refrigerant can be added and the maximum length of refrigerant pipe should not exceed 5 meters(16.5ft).A minimum pipe run of 3 metres is required to minimise vibration & excessive noise. Connection Instructions - Refrigerant Piping.

Step 2: Remove burrs

Burrs can affect the air-tight seal of refrigerant piping connection. They must be completely removed.

• Hold the pipe at a downward angle to prevent burrs from falling into the pipe.
• Using a reamer or deburring tool, remove all burrs from the cut section of the pipe.

Point down Pipe Reamer

Step 3: Flare pipe ends

Proper flaring is essential to achieve an airtight seal.

• After removing burrs from cut pipe, seal the ends with PVC tape to prevent foreign materials from entering the pipe.
• Sheath the pipe with insulating material.
- Place flare nuts on both ends of pipe. Make sure they are facing in the right direction, because you can't put them on or change their direction after flaring.

Flare nut Copper pipe

• Remove PVC tape from ends of pipe when ready to perform flaring work.
• Clamp flare form on the end of the pipe. The end of the pipe must extend beyond the edge of the flare form in accordance with the dimensions shown in the table below.

Air Evacuation

NOTE : PREPARATIONS AND PRECAUTIONS

Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold gauge to evacuate the refrigerant circuit, removing any non-condensable gas and moisture from the system. Evacuation should be performed upon initial installation and when unit is relocated.

BEFORE PERFORMING EVACUATION

√ Make sure the connective pipes between the indoor and outdoor units are connected properly.
☑ Check to make sure all wiring is connected properly.

Evacuation Instructions

Indoor unit Outdoor unit Manifold valve -76cmHg Compound gauge Pressure gauge Low pressure valve High pressure valve Pressure hose or Charge hose Low pressure valve Charge hose Vacuum pump Step • Co ga lo • Co m • O ga • Tu sy • Ru ur (-) • Cl ga • W ha

Step 1:

• Connect the charge hose of the manifold gauge to service port on the outdoor unit's low pressure valve.
• Connect another charge hose from the manifold gauge to the vacuum pump.
• Open the Low Pressure side of the manifold gauge. Keep the High Pressure side closed.
• Turn on the vacuum pump to evacuate the system.
• Run the vacuum for at least 15 minutes, or until the Compound Meter reads -76cmHG (-10 Pa).
• Close the Low Pressure side of the manifold gauge, and turn off the vacuum pump.
• Wait for 5 minutes, then check that there has been no change in system pressure.

Flare nut valve body valve stem Cap

Step 2:

• If there is a change in system pressure, refer to Gas Leak Check section for information on how to check for leaks. If there is no change in system pressure, unscrew the cap
• from the packed valve (high pressure valve). Insert hexagonal wrench into the packed valve (high pressure valve) and open the valve by turning the wrench in a 1/4 counterclockwise turn. Listen for gas to exit the system, then close the valve after 5 seconds.
• Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. The Pressure Gauge should read slightly higher than atmospheric pressure.
• Remove the charge hose from the service port.
• Using hexagonal wrench, fully open both the high pressure and low pressure valves.
• Tighten valve caps on all three valves (service port, high pressure, low pressure) by hand. You may tighten it further using a torque wrench if needed.

OPEN VALVE STEMS GENTLY

When opening valve stems, turn the hexagonal wrench until it hits against the stopper. Do not try to force the valve to open further.

NOTE ON ADDING REFRIGERANT

Some systems require additional charging depending on pipe lengths. The standard pipe length varies according to local regulations. For example, in North America, the standard pipe length is 7.5m (25'). In other areas, the standard pipe length is 5m (16'). The refrigerant should be charged from the service port on the outdoor unit's low pressure valve. The additional refrigerant to be charged can be calculated using the following formula:

ADDITIONAL REFRIGERANT PER PIPE LENGTH

Connective Pipe Length (m)	Air Purging Method	Additional Refrigerant
≤ Standard pipe length	Vacuum Pump N/A
> Standard pipe length	Vacuum Pump	Liquid Side: ∅ 6.35 (1/4")R410A:(Pipe length - standard length) x 15g/m(Pipe length - standard length) x 0.16oZ/ftR32:(Pipe length - standard length) x 12g/m(Pipe length - standard length) x 0.13oZ/ftR22:(Pipe length - standard length) x 20g/m(Pipe length - standard length) x 0.21oZ/ft	Liquid Side: ∅ 9.52 (3/8")R410A:(Pipe length - standard length) x 30g/m(Pipe length - standard length) x 0.32oZ/ftR32:(Pipe length - standard length) x 24g/m(Pipe length - standard length) x 0.26oZ/ftR22:(Pipe length - standard length) x 40g/m(Pipe length - standard length) x 0.42oZ/ft

More features

- Auto-Restart

If the unit loses power, it will automatically restart with the prior settings once power has been restored.

• Wireless Control (Model dependent)

Wireless control allows you to control your air conditioner using your mobile phone and a wireless connection.

For the USB device access, replacement, maintenance operations must be carried out by professional staff.

• Active Clean function(some units)

-- The Active Clean Technology washes away dust when it adheres to the heat exchanger by automatically freezing and then rapidly thawing the frost. A “pi-pi” sound will be heard.
The Active clean operation is used to produce more condensed water to improve the cleaning effect, and the cold air will blow out. After cleaning, the internal wind wheel then keeps operating with hot air to blow-dry the evaporator, thus keeping the inside clean.
-- When this function is turned on, the indoor unit display window appears "CL", after 20 to 130 minutes, the unit will turn off automatically and cancel Active Clean function.

- Louver Angle Memory

When turning on your unit, the louver will automatically resume its former angle.

• Refrigerant Leakage Detection

The indoor unit will automatically display "ELOC" when it detects refrigerant leakage.

- Breezeless function

--The revolutionary double deflectors can bend, veer and soften the airflow to provide multiple levels of softness as you demand.
--Enjoy the cozy coolness with breeze billowing away from you, with mild breeze, or eventually without a noticeable breeze.
--The deflector consist of thousands of hourglass-shaped holes. Each of the micro-holes was specifically designed into hourglass structure in slightly different direction and size, which better pressures and mixes the cool air to provide an immersive cooling experience.

• Oxygen fresh air function

When the Oxygen fresh air function is activated, condensation may occur due to the temperature difference between indoor and outdoor. In order to avoid condensation, the system will automatically adjust the fan speed according to the current operating status. If the condensation risk is still exit, this function will stop and “LC” display on the indoor unit window.

Restart the Oxygen fresh air function by pressing the "Fresh air" button on the remote controlle again.

• Breezeless Operation
